Hello LS-DYNA Community,<\/p>\n

I am currently engaged in simulating rock-like materials using the De_Bond feature in LS-DYNA and have encountered a specific challenge that I hope to get guidance on.<\/p>\n

In my simulations, the rocks are characterized by planar fractures. These fractures are present in two orientations: depth-wise and longitudinally. Notably, the longitudinal cracks exhibit zero cementation strength. My objective is to accurately replicate the behavior of these fractures. To do this, I intend to assign a zero cementation strength to the particles situated along the longitudinal planar fractures at varying depths, while maintaining normal cementation for the remaining particles.<\/p>\n

My queries are as follows:<\/p>\n

    \n
  1. \n

    Does LS-DYNA offer a feature that allows for the importation of planar surfaces? If so, can this feature be used to automatically adjust the bond strength of particles situated along these surfaces?<\/p>\n<\/li>\n

  2. \n

    Is it possible within LS-DYNA to track and quantify specific parameters related to the bond, such as the bond energy and the count of damaged bonds during simulations?<\/p>\n<\/li>\n<\/ol>\n

    I believe these functionalities would greatly enhance the accuracy of my simulations. Any insights, suggestions, or guidance on how to approach this within LS-DYNA would be greatly appreciated.<\/p>\n

    Thank you in advance for your assistance.<\/p>\n","protected":false},"template":"","class_list":["post-318721","topic","type-topic","status-closed","hentry","topic-tag-LS-DYNAruntime-1","topic-tag-apdl","topic-tag-cfd-dem","topic-tag-discrete-phase"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
